Abstract

PURPOSE:To decrease ununiformity of the pad of spectacles to the skin by laminating a reinforcing sheet formed of a material which is harder to curve than an elastic silicone rubber body on the rear side of the pad plate made of the elastic silicone rubber body. CONSTITUTION:A projecting hole 2 for an attaching boss is provided to the reinforcing sheet 1 so as to penetrate through the central part thereof and the attaching boss 3 is tightly fitted through said hole. The plate surface of a substrate 5 on the attaching boss side is adhered and superposed to and on the sheet 1 by matching the substrate 5 provided successively to the root end of the boss 3 and the longitudinal direction of the sheet 1. A synthetic resin 6 liquid is dripped to the plate surface of the substrate 5 on the sheet 1 on the side opposite from the attaching boss and is cured to cover the substrate 5 superposed on the sheet 1 with the synthetic resin. The board bean-shaped pad plate 7 is thus formed of the elastic silicone rubber body on the side of the sheet 1 attached with the substrate.

Description

【発明の詳細な説明】 本発明は、鼻に当接する当板をシリコーンゴム弾性体で
形成した眼鏡の鼻当てに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nose pad for eyeglasses in which a contact plate that contacts the nose is made of silicone rubber elastic material.

従来、この種の鼻当ては、シリコーンゴム弾性体で形成

良好になるように。Conventionally, this type of nose pad has been constructed by embedding a board connected to the base end of a metal mounting boss on the back side K of a contact plate made of silicone rubber elastic material, and placing the mounting boss at the center of the back surface of the contact plate. stands out from Also, make sure that the contact of the plate against the skin of your nose is good.

皮膚への当りが非常に弱くなり、当板は、中央部と端部

果が悪くなる。The hardness of the silicone rubber elastic body is selected. However, the contact plate has a strong contact with the skin at the center part of the mounting boss where the board is buried, and has a weak contact with the skin at the curved end where the board is not buried. Therefore, if the hardness of the silicone rubber elastic body is selected so that the center part of the plate will have good contact with the skin, the edges of the plate will be more likely to curve.
The contact to the skin becomes very weak, and the contact between the center and the edges of the plate becomes very uneven, resulting in poor wearing comfort and anti-slip effect.

本発明の目的は、上記のような欠点を有する従来品の改

供することである。An object of the present invention is to improve the conventional products having the above-mentioned drawbacks, and to provide a nose pad for glasses that has less uneven contact with the skin.

層したことを特徴とする眼鏡の鼻当てである。The present invention provides a nose pad for glasses in which a mounting boss base plate is embedded in a backing plate formed of a silicone rubber elastic body, and the mounting boss protrudes from the back side of the backing plate. This nose pad for eyeglasses is characterized by laminating reinforcing sheets made of materials that are difficult to wear.

小さい。従って、装用感と滑止効果が良好である。This nose pad has a reinforcing sheet made of a material that is less bendable than the silicone rubber elastic material laminated on the back side of the patch plate made of the silicone rubber elastic material, so compared to conventional products that do not have a reinforcing sheet, The part where the board is not buried is difficult to bend, and the uneven contact between that part and the part where the board is buried is small. Therefore, the feeling of wearing and the anti-slip effect are good.

次に、本発明の実施例について説明する。Next, examples of the present invention will be described.
